fluorescent tube chemicals

Fluorescent lamp - WikipediaUltraviolet photons are absorbed by electrons in the atoms of the lamp's interior fluorescent coating, causing a similar energy jump, then drop, with emission of a further photon. The photon that is emitted from this second interaction has a lower energy than the one that caused it. The chemicals that make up the phosphor are.fluorescent tube chemicals,Why are Fluorescent Light Bulbs Dangerous? - Softpedia NewsApr 11, 2008 .
